Summary
Built in 1968, this private-owned earth dam stands at a height of 15 feet with a length of 600 feet, providing a storage capacity of 250 acre-feet. While it does not have a spillway, the dam is equipped with one outlet gate for water release.
Despite being classified as having a high risk level, the condition assessment of the Wheeler Lake No 2 Dam is currently not rated. The dam is not state-regulated but undergoes regular state inspections and permitting. It is situated along TR-LA JARITA CREEK and falls under the jurisdiction of the Fort Worth District of the US Army Corps of Engineers. With its strategic location and vital role in water resource management, the Wheeler Lake No 2 Dam is a key structure for the surrounding community.
Water resource and climate enthusiasts would find the Wheeler Lake No 2 Dam an intriguing example of a privately-owned earth dam that plays a crucial role in fire protection, stock management, and fish pond operations. As a part of the local infrastructure, this dam provides essential services while also presenting challenges related to its high-risk classification. With its historical significance and ongoing maintenance, the Wheeler Lake No 2 Dam exemplifies the intersection of human engineering and natural resource management in the context of climate resilience and water security.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
